=§ 75. Formal organization.=--In 1838 the first formal organization of the Underground Railroad was made, with Robert Purvis as President. It was said that two marketwomen in Baltimore were their best helpers. They had come into possession of a number of passports, or "freedoms," which were used by slaves for part of the distance, and then were returned to serve the same purpose again.[251] In all transactions connected with this organization the greatest secrecy was necessarily observed, seldom more than two or three persons at a station being allowed any knowledge of it. In the Liberator of 1843, a notice is found cautioning people against exposing in any way the methods used by fugitives in escaping, as it only helped the pursuers in the next case. The fugitives themselves were usually careful in this respect. Frederick Douglass absolutely refused until after the abolition of slavery to reveal the method of his escape.[252] Mrs. G. S. Hillard, of Boston, was in the habit of putting fugitives in an upper room of her house. A colored man was placed there, and when Mrs. Hillard went up to see him, she found he had carefully pulled down all the shades at the windows. She told him that there was no danger of his being seen from the street. "Perhaps not, Missis," he replied, "but I do not want to spoil the place." He was afraid lest some one might see a colored face there, and so excite suspicions injurious to the next man.[253] =§ 76. General effect of escapes.=--Although many fugitives were aided previous to 1850, it was after the new law went into effect that the great efforts of the Abolitionists were centred on this form of assistance. Of such importance did it become, that at the beginning of the Civil War one of the chief complaints of the Southern States was the injury received through the aid given their escaping slaves by the North.[254] It was, however, really the "safety valve to the institution of slavery. As soon as leaders arose among the slaves who refused to endure the yoke, they would go North. Had they remained, there must have been enacted at the South the direful scenes of San Domingo."[255] [Footnote 216: Still, Underground Railroad, 410.] [Footnote 217: Ibid., 444.] [Footnote 218: F.
